So my iPhone 4 hasn't been able to connect to any computer (pc or Mac) for a few months, I got tired of it so I decided to do an ota erase all content and settings restore. My phone is jail broken, but now after doing so it is stuck in thE rotating loading circle screen, and it's been 2&1/2 hours.... Can I hold the power and home buttons down and reset it or will it brick my phone? Or any solution would be helpful! Thanks!
